Application filed May 6, 1916. Serial No. 95,92

- To all 'whom it may concem:

Be it known that I, LAWRENGE E-.CON- NELLY, a citizen of the United States, residing at Cleveland, in the County' of Cuyahoga and State ofOhio, have invented certain new` and useful 'Improvements in Clean-Out Flues for VVater-Tube Steam- Generators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will. enable others skilled in the art to which it appertains to make and use the same, reference being had to the aecompanyng drawings, and to the letters of reference marked thereon, this specification'.

My invention relates to steamgenerators,

forming part of 'and especially .to water tube steam generators wherein there are pockets between the baflle walls and the side walls of the boiler setting,

in which soot andj dust will accumulate and it consists in providing a flue through which 'said soot and dust may .be conveyed into the chamber behind the fire-wall of 'the boiler setting( The features of my invention are herinafter fully described and pointe d out, and

are illustrated in the aceompan yin'g draw ings, in which Figure 1, is a vertical section of the boiler setting with a water tube steam generator in place therein, showing my invention installed therein. Fig. '2, is a t'ansverse Section -of a fragment of the same, showing an edgewise V ew of my invention. Fig. 3, is a side view 0:. my soot flue removed fr'm theboiler settin E fil- 'these drawings A, indicates a *mud drum, and A", A and A indicate the upper drums of the water tube boiler, which drums are connected by water tubes B, B', Bf", B and B?, andwhich is installed in the usual boiler Walls D, D D and D which baffle walls are continuous from side to side of the boiler setting: there is; therefore, between the baiiie walls'D' and D?, a pocket having the drum A, as the bottom thereof, in which dust and soot accumulate.

One one end of the drum A, and prefernbly embndicd in one ot' the side walls, C, I place a hollow scgmcntal flue E, having ing E', in the wall thereof, adjacent to the water tubes B'. The lower end of the flue E, 'is provided with a door E which 'is hingod to the body of the flue E, and is pro:

vided with a rod F, which extends outwardly Specification of Letters Patent.

' and ashes off'of the drum A,

is but one pocket,

setting C, and is provided with baiiiean open-' CLEAN-OUT' FLU FOR WATER-TUBE STEAM-GENERATORS.

Patented Oct. 10, 1916.

through the rear wall tof the boiler setting, where it is provided with a handle F', by means of which the rod F, may berotated to open the door E when it is'desired to clean out the soot and ashes from the pocket be tween the baflie walls D' and D At the opposite side of the boiler setting C, I provide adoorG through which a steam lance may be inserted wh'enit is desired to blow the soot flue E.

In operation whenit is operated to open the door E and while the door E is open, a steam lance or other suitable tool may be inserted through the door G, and the ashes forced into the opening E', of the flue E, and thence through the flue into the chamber under the drum A, when the door E can be again closed, and the ashes and soot removed through the doorH, in the rear wall of the boiler setting, when desired; The door E at the lowerend of theflue E', prevents the by-pass of the furnace gas from the space between the bathe walls D' and D and likewise prevents the into.said space.

While I have shown my invention as applied to the Water tube boiler in which there wherein ashes may accumulate, it is obvio'us that the'opening E', may be made sufiiciently extensive to receive ashes from more than. one pocket above the'dru A, without departing from the scope of invention.

Therefore, having described the Construction and operation of my invention, so as to enable others to utilize the same, what I claim as new and desire' to obtain by Letters- Patent, is

and into the is desired tb'clean 'the ashes ofl' of the drum A, the handle F',

"passage of cool air from the rear chamber 1. The combination in a water tube boiler,

of'a lower drum, a plurality'of battle walls in spaced relation to each other and extending upwardly from said drum, a flue at one end of said drum' commmcating with the spacehetween said bafiie Wa'lls and terminating behind said drum, and means to close the exit end of said flue, substantially as de scribed. V

2. The eombination in a water tube boiler, 'of a lower drum, a plurality of baiiie walls in spaced relation to each 'other and extending upwardly from said drum, side walls closing the spaces between the edges of said baflie walls, a segmental flue embedded in' one of aid side ;Walk around sa'ddru'm, and having an openmg which communicates Wbh the space between said bafie-walls, and an opening which co'mmunicates With a ohamber be- 5 hind said drum, and means to open and close the last mentoned opening, substantially as escrbed. 1

. 3. The combnation in a Water tube boler,

of a series of beme Walls in space& relaton,

a transvefise 'fire-wall, and a clean-out flue 10 communcating With the space between said bafe-walls'and the chamber behind said fire- Wall, substantially as described..

In testimony Whereof I afix my signature.

LAWRENCE E. CONNELLY.
